A new rhodium(l) catalyst allows practical and efficient alkyne carbothiolation reactions to be achieved on synthetically useful ketone-bearing aryl methyl sulfides. The carbothiolation adducts, featuring a 'recycled methyl sulfide' activating group, are convenient precursors to highly substituted isoquinolines.

rhodium complexes containing methylene bridged diphosphine ligands, viz. [Rh(C(6)H(5)F)(R(2)PCH(2)PR'(2))][BAr(F)(4)] (R, R' = (t)Bu or Cy; Ar(F) = C(6)H(3)-3,5-(CF(3))(2)), are shown to be practical and very efficient precatalysts for the intermolecularhydroacylation of a wide variety of unactivated alkenes and alkynes with β-S-substitutedaldehydes. Intermediate acyl hydride complexes [Rh((t)Bu(2)PCH
